Wildlife Travel Burren 2018
The Burren 2018 species list and trip report, 7th-12th June 2018 WILDLIFE TRAVEL The Burren 2018 s 1 The Burren 2018 species list and trip report, 7th-12th June 2018 Day 1: 7th June: Arrive in Lisdoonvarna; supper at Rathbaun Hotel Arriving by a variety of routes and means, we all gathered at Caherleigh House by 6pm, sustained by a round of fresh tea, coffee and delightful home-made scones from our ever-helpful host, Dermot. After introductions and some background to the geology and floral elements in the Burren from Brian (stressing the Mediterranean component of the flora after a day’s Mediterranean heat and sun), we made our way to the Rathbaun, for some substantial and tasty local food and our first taste of Irish music from the three young ladies of Ceolan, and their energetic four-hour performance (not sure any of us had the stamina to stay to the end). Day 2: 8th June: Poulsallach At 9am we were collected by Tony, our driver from Glynn’s Coaches for the week, and following a half-hour drive we arrived at a coastal stretch of species-rich limestone pavement which represented the perfect introduction to the Burren’s flora: a stunningly beautiful mix of coastal, Mediterranean, Atlantic and Arctic-Alpine species gathered together uniquely in a natural rock garden. First impressions were of patchy grassland, sparkling with heath spotted- orchids Dactylorhiza maculata ericetorum and drifts of the ubiquitous and glowing-purple bloody crane’s-bill Geranium sanguineum, between bare rock. A closer look revealed a diverse and colourful tapestry of dozens of flowers - the yellows of goldenrod Solidago virgaurea, kidney-vetch Anthyllis vulneraria, and bird’s-foot trefoil Lotus corniculatus (and its attendant common blue butterflies Polyommatus Icarus), pink splashes of wild thyme Thymus polytrichus and the hairy local subspecies of lousewort Pedicularis sylvatica ssp.

(Salicaceae sensu stricto) are discussed and some suggestions and conclusions made about how to deal with them. Keywords: challenges, identification, naming, Populus, Salix, Salicaceae Introduction Botanists and other researchers who, directly or indirectly, are involved with plants in their work should answer three main questions: (1) Which taxon does a plant belong to? (2) What is the correct name of this taxon? (3) What relationship does this taxon have with other taxa? To answer these questions, one should understand the principles and basics of (1) taxonomy, (2) nomenclature and (3) systematics or phylogenetics, none of which can exist separately from each other. For example, while working on the taxonomy of weeping willows (Belyaeva et al., 2018), I wondered if the weeping willow in Monet’s pictures, the weeping willows growing on the streets in Paris and the weeping willow cultivated at the Royal Botanic Gardens, Kew are the same taxon (Fig. 1) and if these willows have the same scientific name.

Ph.D. Thesis Series, No. 9. University of South Bohemia, Faculty of Science, School of Doctoral Studies in Biological Sciences, České Budějovice, Czech Republic, 183 pp. Annotation The aim of this dissertation is to investigate what role insect-plant interactions play in the formation of host-plant defenses and in the diversification of both groups. We show that various groups of herbivore respond differently to host-plant defenses. Therefore plant defenses diversify into suites of complementary traits, as individual traits fail to provide protection against specialized herbivores. Further, we identify what levels of host-phylogeny shape the food- web structure of insect herbivores. We show that specialized herbivores are affected mainly by the terminal parts of the host- phylogeny. In contrast, more polyphagous guilds are affected mainly by the mid-levels of the host phylogeny because the effects of terminal or deeper phylogeny seem to be surpassed by other factors in more generalist insect species. In the last chapter, we show how specialized insect-plant interactions generated by tight insect-plant coevolution can influence the speciation in plants over environmental gradients.

Continuing on our way to the National Museum we passed a statue to Molly Malone outside Trinity College. A brief stop at the National Library of Ireland to marvel at its impressive domed Reading Room. The archaeological exhibitions at the National Museum superbly traced the development of Irish civilisations, and the collections included the Cloth of Gold from Glenisheen - a wedge tomb we’d see later in the week in the Burren. After a coffee at the museum’s café we made our way to Heuston to catch our train to Galway.

Fourteen Salix taxa were found, among which were several rare or very rare hybrids, such as Salix × capreola A.Kern. ex Andersson, S. ×charrieri Chass. and S. × subsericea Döll. The latter hybrid must have originated from a cultivated S. repens. An as yet unidentified willow has been encountered, which is likely a hybrid of a non-native Salix in the outdoor collections. The richest willow flora occurs around the lakes and in the semi-natural moist woody areas. Some willows, such as S. viminalis once grown for basketry near the castle, are descendants of previously existing plantings. It is clear that willows play a significant ecological, economic and cultural-historical role in the MBG domain. Keywords: Salix, escapes, hybrids, Meise Botanic Garden, rare taxa, subspontaneous taxa Introduction Situated 15 km north of Brussels, Meise Botanic Garden (MBG) is a research institution and tourist attraction with large and diverse botanical collections.
